'Gyroscope' molecules form crystal that's both solid and full of motion
To make a solid crystal, molecules are generally so tightly packed together there's no room for any movement. It means that solid crystals -- despite their strength and durability -- have generally been ignored as having any possible function as molecular machines. UCLA researchers have formed a crystal out of molecules that look like gyroscopes. The crystal is externally solid but contains moving parts.

Solid-state physics offers insights into dielectric properties of biomaterials
In this paper, researchers characterize the behavior of proteins, considered as classical amorphous semiconductors, with the help of the formalism of condensed matter physics. The authors have clearly shown the powerful methodology and instrumentation of condensed matter physics to be effective for fundamental research into the electrodynamics of biological objects. The next step could involve the application to biomaterials research of the wide range of other theories and models that have been effectively used by the physics community for many decades.

New long-acting, less-toxic HIV drug suppresses virus in humanized mice
A team of Yale researchers tested a new chemical compound that suppresses HIV, protects immune cells, and remains effective for weeks with a single dose. In animal experiments, the compound proved to be a promising new candidate to enhance current HIV treatment regimens -- without increasing toxic side effects, the researchers said.

Touchy nanotubes work better when clean
Heating carbon nanotubes at high temperatures and slowly cooling them eliminates contaminants that make nanotubes difficult to test for conductivity. Scientists from Rice and Swansea universities show how decontaminated nanotubes may simplify the design and manufacture of nanoscale devices.

Nature's smallest rainbows, created by peacock spiders, may inspire new optical technology
The mechanism behind these tiny rainbows may inspire new color technology, but wouldn't have been discovered without research combining basic natural history with physics and engineering. These super iridescent spider scales can be used to overcome current limitations in spectral manipulation, and to reduce the size of optical spectrometers for applications where fine-scale spectral resolution is required in a very small package, notably instruments on space missions, or wearable chemical detection systems.

Tweaking quantum dots powers-up double-pane solar windows
Researchers at Los Alamos National Laboraotry are creating double-pane solar windows that generate electricity with greater efficiency and also create shading and insulation. It's all made possible by a new window architecture which utilizes two different layers of low-cost quantum dots tuned to absorb different parts of the solar spectrum. The approach complements existing photovoltaic technology by adding high-efficiency sunlight collectors to existing solar panels or integrating them as semitransparent windows into a building's architecture.

Novel nanomedicine inhibits progression of pancreatic cancer in mice
A new Tel Aviv University study pinpoints the inverse correlation between a known oncogene -- a gene that promotes the development of cancer -- and the expression of an oncosuppressor microRNA as the reason for extended pancreatic cancer survival. The study may serve as a basis for the development of an effective cocktail of drugs for this deadly disease and other cancers.

Silver nanoparticles take spectroscopy to new dimension
As medicine and pharmacology investigate nanoscale processes, it has become increasingly important to identify and characterize different molecules. Raman spectroscopy, which leverages the scattering of laser light to identify molecules, has a limited capacity to detect molecules in diluted samples because of low signal yield, but researchers in India have improved molecular detection at low concentration levels by arranging silver nanoparticles on silicon nanowires. They describe their work in this week's Journal of Applied Physics.

Single metalens focuses all colors of the rainbow in one point
Metalenses -- flat surfaces that use nanostructures to focus light -- promise to revolutionize optics by replacing the bulky, curved lenses currently used in optical devices with a simple, flat surface. But, these metalenses have remained limited in the spectrum of light they can focus well. Now a team of Harvard researchers has developed the first single lens that can focus the entire visible spectrum of light -- including white light -- in the same spot and in high resolution.

Now entering, lithium niobate valley
Lithium niobate is already one of the most widely used optical materials, well-known for its electro-optic properties but it is notoriously difficult to fabricate high-quality devices on a small scale using lithium niobate, an obstacle that has so far ruled out practical integrated, on-chip applications. Now, Harvard researchers have developed a technique to fabricate high-performance optical microstructures using lithium niobate, opening the door to ultra-efficient integrated photonic circuits, quantum photonics, microwave-to-optical conversion and more.

Nanofractionation platform with parallel mass spec to ID cytochrome CYP1A2 inhibitors
This new (and freely available) original research article presents a fast, robust and accurate methodology for correlating compound identity to CYP1A2 potency of inhibitors in metabolic mixtures. The methodology is centered around an at-line nanofractionation platform in which a metabolic mixture is chromatographically separated followed by parallel on-line mass spectrometric analysis and at-line nanofractionation on high-density microtiter well plates that are then directly exposed to a bioassay.
